ferently threaded portions. These threaded y shafts are rotatablymounted inthe ends and center of the member 31, as indicated at 34 and35 respectively. j Y

Disposed beneath the member 31'is a con-V veyer or road engaging member36'. This 4meml'aer comprises endless beltsl 37 and 38,'V mounted onroller carrying shafts 39, the shafts 39 being Vin turn connected.through sprockets, the drive chains 40 A with the sprockets mounted onthe shaft 41. Transverse supporting arms 41a are provided for,stabilizing the skeleton `frame of the con'- veyer- 36. The gear 42 alsomounted on the shaft 41 is adapted to mesh With the gear24gpreviously`referred to.

Pivotally connected to leach end ofthe conveyer member 36 is a pairofsupporting arms 43 and 44. The opposing ends of these arms, asparticularly illustrated` in Figure 2, arev pivotallyyconnected byAmeans of Vthe threaded collars 45and 46, tothe threaded shafts 32 and 33respectively.l

The drive means 4forthe threaded shafts 32 and '33 and the conveyer 36are clearly fillustrated in Figures 3and 4.` rlhe threaded' 'shafts 32'and 33v are provided substantially midway thereof, with bevel gears 47and 48. i

i or driving purposes.

Yis provided with suitable Meshing Withl the gears `47 and 48 `areafurther pair of bevel gears 49 and 50 Which aremounted on the crossshafts 51'and. 52.

The shafts 51 and52 are supported in suitable bearings 53 and areprovidedrat their inner ends with further bevel .gears 54 and 55, whichare driven bythe gear 56 mounted on the shaft 16, Which also causes litsdriving gear 57 to .mesh With thegear 26. Y y

VDuring the'operfationof parking the motor vehicle, the conveyer 36 isirstlovvered in such a manneras to'elevate the car for parking purposesand after it'has performed its op- Y eration, is collapsed so as toprovide suiicient road clearance. In order to take care of the HexibleVdrive means for the conveyer When eitherin operative or collapsedposition, some means must be provided to absorb the slack of thecenveyer drive chains. In the present instance' I provide 'the rollercarrying members 58V whichv may conveniently be spring connected to thechassis of the vehicle, so that as the conveyer 36-i'smoved from anoperative to' a; collapsed position, the `spring actuated members 58Will eXerta pull on any slack created in the drive chains 40 duetothecollapsing operation andthus theA drive chains are always properlytensioned for operating Coming now to the meansby-fvv'hich the motorvehicle is rotated,this comp-rises a vcomparatively1 large bevel "gearV59 securelyv fixed to the face of the member 31V andn with whichthebevel gear 22 is adapted to mesh. The inne-r periphery of the gear 59and meme ber 31 vvith-in Whiclrthe'flange 16 is carried ball-bearingsindicatedat 60. i

@Wing to the central position lof the parking device,'vvhichj`ivould bepositioned in the vehicle frame at Vthe center of' gravity, provision ismade for carrying the drive shaft over the top ofl the ydevice A. Anyconvenient means'` may be Aemployed and I have in- 26, 57 56,149', 59,47 and 4 8, and through then-1 rotate the threaded-shafts 3-2 and-33,causing thearnigs 43Qand 144 tofhe pulled together.AThisaccorrlir1glywill cause the downward movement of the. conveyor.3,6pY When the member 36 hasbzeen sufli'ciently extended to elevate themotorvehicle, the

gear 27" is then moved out of mesh with 'the if and 42 and the chains 40which vin turn,

through the shafts 39, operate the conveyer members 37 and 38 will movethe motor vehicle either right or left as desired to a parking position.In order to restore ythe parking device to its normal inoperativeposition, the operation just described, is re versed. This iseffectively accomplished by operating the reverse gear 29. Y

Should it be desired toturn the vehicle upon its aXis, the gear 27 ismoved into mesh with the gear 21. This will rotate the shaft 18 and withit the bevel gear 22 which Vis in mesh with the gear 59, mounted on themember 31. This operation will cause the vehicle as a whole to be turnedto any desired position. f

In the vmodified form of device, as illustrated in Figure 7, thestructure and operation is substantially the same as that illustrated inFigure 2. The difference in the two structures resides mainlyin themeans provided for operating the conveyer irrespective of the relativepositionjof the members 10 and 11. p

This difference in structure mainly comprises the bevel gear 65 which issubstituted for the gear 24 which meshes with the double faced gear` 66which in turn meshes with the Y a and a power transmission, of an upperunit bevel gear 67 mounted on the shaft 41 which forms the driving meansfor the conveyer 36.

It will be observed from the structure illustrated in this connection,that irrespective of the position of the member 10 with respect to themember 11, the conveyer 36 may be operated. In addition to theforegoing, I provide means for indicating the relative position of theconveyer with respect to the directional movement of the vehicle itself.This means comprises a sprocket mounted on the hollow shaft 18 which isconnected by means of a belt or chain 68, to a sprocket on the shaft 69,which operates the. indicator 70 conveniently mounted on the instrumentboard, andtlius enables-thedriver of the' vehicle vto visualize thepositionfof the conveyer prior to parking or unparking the motorvehicle. n a

In the further modification illustrated in Figure 8, which effects theturning operation,

I substitute the worm gear 71 for the gear L 59 and operate this gearthrough themedium preted as illustrative sense.
